FPR

Description

Pictures below show my experimental version of self-made laser jammer. It is experimental version only since their usage is not legal in my country.

Receiver is similar to receiver used in optical datalink RONJA. 3 IR photodiodes followed by MOSFET amplifier BF998, video amplifier NE592 and fast comparator. Transmitter is similar to blinders transmiter but laser diode was used instead of IR LEDs.

This jammer was tested against ProLaser III and LTI. Single unit was able to defeat speed measuremnt down to 60 meters. Two units were able to fully defeat speed measurement (what was a big surprise).

Nor schematic neither source code is available. Do not ask me for it.
